java - 根据日期从 MySQL 数据库中获取数据

Question

我有一个名为 Order 的表，包含 3 列（id、date、price）。我正在尝试检索date >= startdate AND date <= endDate. 列date中的日期保存为TEXT以下格式："MM-dd-yyyy HH:mm:ss"( 10-27-2013 12:12:43)

我尝试了以下 SQL 语句：

Cursor cursor = cr.query(PizzeriaContentProvider.CONTENT_URI_ORDER, null, PizzeriaDatabase.CELL_ORDER_DATE + " >= DATETIME ("+ startDate + ") AND " + 
                PizzeriaDatabase.CELL_ORDER_DATE + " <= DATETIME(" + endDate + ")", null, null);

Cursor cursor = cr.query(PizzeriaContentProvider.CONTENT_URI_ORDER, null, PizzeriaDatabase.CELL_ORDER_DATE + " between ( " + startDate + " AND " + endDate + ")", null, null);

但是他们都抛出了同样的异常：

java.lang.RuntimeException: Unable to start activity ComponentInfo{cz.vongrad.pizzeria/presentationLayer.ViewOrder}: 
android.database.sqlite.SQLiteException: near "14": syntax error: , 
while compiling: SELECT * FROM orders WHERE (date >= DATETIME(10-27-2013 14:01:53) AND date <= DATETIME(10-27-2013 14:01:53))

所以我想我以错误的格式比较日期？

倒置逗号丢失::

Cursor cursor = cr.query(PizzeriaContentProvider.CONTENT_URI_ORDER, null, PizzeriaDatabase.CELL_ORDER_DATE + " >= DATETIME ('"+ startDate + "') AND " + 
                PizzeriaDatabase.CELL_ORDER_DATE + " <= DATETIME('" + endDate + "')", null, null);
